LSPV (Load Sensing Proportioning Valve) ASSEMBLY (If equipped)
As shown below, LSPV is included within the brake circuit which connects the master cylinder and the rear wheel
brake. It controls the hydraulic pressure applied to the rear wheel brake according to the loaded state of the vehicle
(or weight of the load), whereby preventing the rear wheels from getting locked prematurely. Also, it releases the
above described control over the hydraulic pressure applied to the rear wheel brake, should any failure occur in
the hydraulic circuit of the front wheel brake so that the hydraulic pressure produced in the master cylinder is ap-
plied to the rear wheel brake directly to operate it.
CAUTION:
Never disassemble LSPV. Disassembly will spoil its original function. If faulty condition is found, re-
place it with new one.
1. LSPV spring
2. LSPV assembly
3. From master cylinder (Secondary)
4. To rear wheel brakes (Right and Left)
5. From master cylinder (Primary)
6. Loaded
7. Empty
CONSTRUCTION
The LSPV components are grounded into 3 sections as follows.
“A”:
Sensor section
The main parts in this section are a lever and a spring which senses variation in the vehicle height as affected
by the loaded condition and convert it into the load.
“B”:
Hydraulic pressure control section
Included in this section are a plunger and valve mechanism to execute proportional control.
“C”:
Fail-safe section
The main part in this section is a chamber which draws in the hydraulic pressure from the front wheel brake
system and a fail-safe piston which releases the valve mechanism in the control section connected to the
rear wheel brake, should any failure occur in the front wheel brake system.
1. Plunger
2. LSPV lever
3. Load sensing spring
4. From master cylinder
primary chamber
(Rear wheel brake)
5. To rear wheel brake
6. From master cylinder
secondary chamber
(Front wheel brake)
7. Bleeder plug
8. Collar
Never adjust
